Had a little time yesterday and finally switched out the Sakae CR crankset on the PX10 for a Stronglight 103. Went from 52-42 to 52-38. This should make a much better hill climber - I'm going to have to go find some mountain passes this summer to check that out. Eventually I'll get rid of the Helicomatic rear hub (yes, I like Frankenbikes) so I can have some more options for freewheels. Ideally I'd like a 13-24 6 spd freewheel.
Old crankset:
New look with a Gipiemme rear derailleur to replace the SX630 that I constantly had problems with.
